Comprehensive straw treatment device with squirrel cage tube heat exchanger

Abstract

The invention discloses a comprehensive straw treatment device with a squirrel cage tube heat exchanger. The comprehensive straw treatment device comprises a sine roller, a biogas fermentation tank, abiogas storage tank, a countercurrent drying tower, a biogas burner and a biogas boiler, wherein a sine ultrasonic vibration exciter is arranged at the left lower part of the biogas fermentation tank; the right upper part of the biogas fermentation tank is connected with the bottom of the biogas fermentation tank through a pipe and a Roots blower; an outlet of the Roots blower is connected with the biogas storage tank; the biogas storage tank is connected with the biogas boiler through a pipe and the biogas burner; the biogas boiler is connected with the countercurrent drying tower through asteam fin heat blower; the left upper part of the countercurrent drying tower is sequentially connected with a spiral closed feeder and the sine roller; and a cosine rubber disc pulse burst device isarranged at the left lower part of the countercurrent drying tower. The sine roller, the cosine rubber disc pulse burst device and the sine ultrasonic vibration exciter of the comprehensive straw treatment device have distinctive characteristics, and can reliably and cooperatively achieve comprehensive development and utilization of crop straws and wastes with particularly large water content gradients.

Description

technical field [0001] The invention relates to a straw comprehensive treatment device with a squirrel cage type tube heat exchanger. Background technique [0002] Crop stalks and agricultural waste are the main garbage and waste in the agricultural industry. Nowadays, agricultural waste is generally treated by crushing straw and returning it to the field, burning it and making biomass fuel, but returning the straw to the field cannot make the energy rich in it effective. Utilization and production of biomass fuels have high requirements on the moisture content of agricultural wastes, and incineration is particularly polluting to the environment. Therefore, it is difficult to efficiently and comprehensively treat agricultural wastes with different moisture content and to carry out efficient waste utilization. If a more advanced straw comprehensive treatment device with a squirrel cage heat exchanger can be designed, it is suitable for processing agricultural waste with a lar...
